Applicationifiled August 28, 1911. Serial No. 646,313.

To all whom it may (me n: I

. Be it knownthat I, JOA UIN GARCIA on QUEsAnA, manufacturer, a subyect of the King of Spain, residing atBarcelona, in the Province of Barcelona and Kingdom of Spain, have invented certain new and use- .tul Improvements in 'Befrigerating Apparatus; and I do'hereby-declare the follow 'ing to be a full, clear, "and exact description of the invention, such as will enable others skilled in the art to which it appertai'ns to make and use the same.

My invention relates to an improved refrigerating apparatus, and it consists in the constructions, combinations and arrangements herein described and claimed.

An object of my invention is to provide a simple and compact refrigerating apparatus comprising a portable generator having a source of gas under pressure and an absorbent for such gas, adapted to be detachably secured to any suitable cooling coil and to constitute with said coilaclosed system for the expansion, circulation and condensation or absorption of a gas; thereby providing a convenient and economical-apparatus for domestic use, in which expended generators can be readily detached from the cooling coil and replaced by charged generators, and the gas recovered from the absorbers of expended generators and compressed for recharging the same.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views :-Figure 1 1s a sectional view on the line 1-1 of Fig.2, illustrating one embodiment of my invention; and, Fig. 2 is a section on the line IIH of Fig. 1.

- Referring to the drawings, 3 indicates a perforated casing having a cover 4 secured thereto by bolts 5.

A container, or-tank, 8 for strongly compressed orliquefied gas is provided with an outlet valve having a hand Wheel 9 in position for convenient operation through an opening in the casing 3 provided with a pivoted cover plate 7. An outlet pipe 10, from said container, is. provided with a regulating valve 11, and 1s adapted to be detachably connected by a union 12 to the valved inlet 22 of any suitable cooling coil 24:.

A closed receptacle is divided by a horiaontal partition 15 into a. lower compart- Specification of Letters Parent-k -1ng within a window G in the casing 3".

ment 13 for containing a'suitableabsorbent i for thegas and an upper overflow com-para ment- 17. communicating therewith through an aperture let in said partition for permitting expansion of such absorbent during operation; said overflow compartment being provided with a relief valve19, and with a gage 18 positioned for-"convenientread- Any suitable gas and absorbent maybe employed, and I have found ammoniacal gas and Water to prove entirely satisfactory.

As water is-absorbing ammonia increases in volume in proportion to the amount of gas absorbed, the amount of ammonia drawn from the receptacle 8 can be determined hy reading the water level in the sight gage 18. This arrangement of the receiver13 and tank 17' provides an advantageous. construction for preventing violent shifting of the contained water during handling and use.

A pipe 16, provided with a valve 20, is detachably connected by a union 21 with the valved outlet pipe 23 of the coil, andem tends through the overflow compartment 17 to the lower portion of the lower compartment. Suitable braces QS and 29 are shown for supporting the container and receptacle in the casing 3.

In the operation of my invention, the gas under pressure is admitted to the pipe 10 by turning the hand wheel 9, and the valve- 11 adjusted to regulate "the expansion of such gas supply in the coil 2e; thereby regulatin the rate of supply and degree of expansion within said coil. After cooling the coil by circulating therethrough, the gas is discharged into the lower compartment 13, where it is absorbed by the absorbent mate rial therein; thereby maintaining a reduced pressure on the discharge end of said coil for insuring an efficient circulation there-.

through. I

From the above description, it will be clear that my invention provides a simple and compact refrigerating apparatus comprising a portable generator having a source of gas under pressureand an absorbent for suchgas, adapted to be. detachably secured to any suitable cooling coil andto constitute.

with said coil a closed system for the expanslon, circulation and condensation or absorption of a gas; thereby providing a convenient and economical apparatus for domestic use, in-which expended generators can be readily detached from the cooling coil and replaced by charged generators, and

the gas recovered from the absorbers of expended generators-and compressed for recharging the same.

claim 1. In a refrigerating apparatus provided with a cooling coil, the combination of a portable generator comprising a container for gas under pressure and a. closed receptacle divided by an apert-ured partition into a lower compartment for normally containing anabsorbent of such gas and a communicating upperoverfiow compartment av water glass on said overflow compartment, a valved pipe communicating with the lower portion of said lower compartment, a valved pipe leading from said container, and means for detachably securing said container pipe and lower compartment pipe respectively to the inlet and outlet of the coil.

2. In a refrigerating apparatus provided Q valved pi e communicating with the lower portion 0 said lower compartment, a valved pipe leading 'from said container, means for detachably securing said container pipe and lower compartment pipe respectively to the inlet and outlet of the coil, and valves in said inlet and outlet.

In testimony whereof, I aflix my signa ture, in presence of two witnesses.
